I am trying to inject one droplet in a 2d domain, but in the Injection set up, the droplet option cant be chosen, is there a way to activate the droplet option? I have been looking for hour in the fluent user guide

This is an old unanswered message but I have the same issue... I want to predict the evaporation of water droplets but I can't manage to check the droplet box in the "Injection" window.

I've read in the Fluent User Guide that the "heat transfer model" must be activated but this is already the case... Moreover, I've checked the "droplet" box in the "Discrete Phase" window (--> Numerics --> Coupled Heat-Mass solution) but nothing changes...
